Document Summary
Intelligence, pt3 (the origins and ethics of intelligence) 100: in this situation, environment is identically good for everyone and genetic variability is primarily responsible for phenotypic variability in height (h2 is very high here). Origins: genetics: h2 is frequently misunderstood and misused, consider a group of people that differ in height. 100: in this situation, environment is variable between people, and even with identical genetic range as before, environment account for a lot of height variability (h2 is moderate). Origins: genetics: h2 is frequently misunderstood and misused, now consider the number of digits on your hand. Yes: even though genes determine that we have five digits, the h2 for having five digits is near zero because variability is usually a purely non-heritable environmental factor (accidents)! Origins: genetics: in families, iq correlates a lot between siblings and h2 is around 0. 47 (moderate), third variable problem: sibling share much more than just genes!
